FYI IOS 13.2.2 was just released. Hopefully will fix some other crap in the phone as well.

 

Spoke too soon.... updated from 13.2 to 13.2.2.. just tried to have a conference call while driving to work this morning, and the BT connection to PCM was dropped 2 seconds into it and couldn't reestablish BT connection with PCM. Ended up using wireless headphone to complete the calls..

 

Well, that sucks. I will try my again and see if it still happens. I hope they fix this already, it's pretty annoying.

 

News gets worse: now with 13.2.2, connections get dropped in the Cayenne now too. My wife stayed on 13.2 and her exact same phone (11 Pro) still works with both cars.

 

Odd, mine was working- I took a couple of calls over the weekend with no issues. FYI, a new update 13.2.3 was released today, so hopefully that fixes it for you.

 

2009 C4S PCM 3.0
iPhone XS - 13.1.3
Yes - Issues.

I noticed one issue with the Porsche (but don't get many calls in it), but my Motiv ring and my wifes Fitbit are also having intermittent bluetooth connectivity problems. I think it is a bluetooth issue with IOS 13.x in general.
I will install 13.2.3 now and wait and see!

 

Not for me. Still having same issue. Phone initially connects but call drops off bluetooth during call. I have worked with apple and had my PCM updated but still not fixed.
Iphone 11 pro with ios 13.2.3 on 2017 991.2 with PCM 4.1 updated at dealer on 11/27/2019

 

2009 C4S
iPhone X iOS 13.1.3 no issues w/BT
iPhone 11 pro max, got BT connectivity issues with iOS 13.1.3

Installed iOS 13.3 today, BT works fine now.

 

What I learned is that you can disable and enable Bluetooth, forget all paired devices and match again, reset network settings, restore iPhone or set all settings.

Sometimes, there is probably a software crash or bug with the iPhone, so you can try to repair with iOS system recovery, like Repair, UltFix, Fixppo, etc.

Take steps for common solutions first and then try more.

 

As for your problem, you can force restart your iPhone to fix the Bluetooth issue. Or you can use the third-party tools such as TunesKit iOS System Repair to fix your problem.

 

I searched on every forum on internet and eventually end up fixing this by ensuring the Bluetooth is switched on.
